Title: Manufacture of cathode-ray tube
Inventor: OGAWA SHINJI
IPC: H01J29/88
Filed: 1990-05-07
Abstract: PURPOSE:To heighten gettering effects and extend the service life of a cathode- ray tube while keeping the highly vacuum condition in the tube by forming a conductive coating containing activated carbon, which is thermally treated under nitrogen atmosphere or in vacuum, on the surface of the inner part of the tube except the plane coated with a phosphor. CONSTITUTION:To prevent oxidation and burning of interior materials during a sealing process with flits, activated carbon to be used as an interior material is previously heated at 800-3000 deg.C in nitrogen atmosphere or vacuum. The heat treatment is preferably carried out for 5 minutes to 3 hours depending on the temperature of the heat treatment. Further, since unnecessary gases in a tube are adsorbed and removed effectively by the activated carbon composing a conductive coating, deterioration of a cathode of an electron gun is prevented and a long service life is achieved.

Abstract: PURPOSE:To reduce a power consumption, and also to improve a precessing speed by providing a means for changing an oscillation frequency, and changing a machine cycle of an apparatus in accordance with a key input instruction or a program instruction. CONSTITUTION:A CPU1 is in a low speed mode state by connecting a low speed processing oscillator 8 to a clock generator 5, and when inputting a user program, etc. by a key, it is received in this state.

Abstract: PURPOSE:To stop a function as quickly as possible, to protect an electrolytic capacitor and to increase safety be a method wherein, when an internal pressure inside an outer-package case exceeds a reference pressure by an excessive current or the like, a movable conductor installed between a first fixed conductor and a second fixed conductor is moved by the pressure and the connection of a capacitor element is cut off. CONSTITUTION:When a pressure-receiving valve 38 is subjected to a pressure P, the pressure-receiving valve 38 is moved to the action direction of the pressure P from a normal state. When the pressure P exceeds a reference pressure Pr, a skirt part 44 hits the inner wall surface of a guide hole 48 of a stopper 46; it is pressed and compressed; it is passed through the guide hole 48. As a result, a movable conductor 34 is pushed up to the side of a fixed conductor 28 by the pressure-receiving valve 38; the movable conductor 34 is separated from a fixed conductor 30. Consequently, the electrical connection between the fixed conductors 28, 30 by the movable conductor 34 is released; a capacitor element 4 is cut off from an external terminal 16 and its function is stopped; an electrolytic capacitor is protected from an excessive electric current.

IPC: H01L21/302
Filed: 1990-05-08
Abstract: PURPOSE:To realize a high-speed and highly selective etching operation in a microwave plasma etching apparatus by a method wherein a substrate is treated at an electron cyclotron resonance point and a gas of Cl2+O2 is used. CONSTITUTION:A plasma generation chamber 1 which generates a plasma by an electron cyclotron resonance operation is constituted so as to be adjacent to a substrate conveyance chamber 2. The plasma chamber is constituted in a route which matches the condition of a microwave cavity resonator in order to increase the field intensity of microwaves and in order to increase the efficiency of an electric discharge operation. When this method is used, an ion current density is sufficient and a field grade is sufficiently small; as a result, an ion energy becomes sufficiently small. Even an etching operation using Cl2 gas is carried out at sufficiently high speed and the selection ratio to an oxide film at a substratum can be made large. When oxygen is added to the chlorine gas, it is possible to completely restrain SiO2 from being etched selectively; the infinitely great selective ratio to polysilicon can be achieved.
